20080293926 | Preparation of Biomolecules - The present invention relates to a method of separating a target from a liquid, which includes providing a polymer in an aqueous liquid, which polymer comprises at least one hydrophobic portion; contacting the polymer-containing liquid with the liquid comprising the target; applying a stimulus to the resulting mixture; and maintaining it until a reversible phase separation is obtained. One phase is polymer-rich and contains target(s) and another phase is polymer-poor. By either maintaining the stimulus, or applying a different stimulus and maintaining it, the polymer-rich phase is transformed into a substantially solid phase. | 11-27-2008 |

Each treatment step occurs within the same reaction compartment. The reaction conditions of each reaction compartment for treating a slide can preferably be controlled independently, including the individualized application of reagents to each slide and the individualized treatment of each slide. | 10-29-2009 |
20090281289 | METHOD AND APPARATUS FOR EXTRACTION OF ARTHROPOD GLAND - Apparatus and method for the extraction of material from glands of arthropods. The apparatus includes a container in which at least part of the glands are placed and a buffer solution at least partially immersing the glands. Gland material is collected in the material collection area of the container, e.g., by release of the material from the glands into the buffer solution and sedimentation of the material at the bottom of the container. The method involves removing from a body of the arthropod the gland containing at least partially the material, making an opening in an epithelium of the gland, and placing the gland in the container at least partially immersed in a buffer solution, so that the material exits the glands and sediments in the material collection area of the container. | 11-12-2009 |
20090306354 | EGGSHELL MEMBRANE SEPARATION METHOD - A method for processing unseparated egg shells is provided. The method includes placing the unseparated egg shells in a fluid tank containing a fluid mixture, applying cavitation to the fluid mixture to thereby assist in separating the egg shell membranes from the egg shells, and recovering the egg shell membranes. Preferably, the fluid mixture is recirculated to thereby provide for continuous processing of unseparated egg shells. The method may further include drying the egg shell membranes to produce dried egg shell membranes which may then be vacuum packaged for storage and/or transport. The dried egg shell membranes may then be subjected to an extraction process for extracting at least one type of polypeptide from the egg shell membranes. Collagen, hyaluronic acid, or amino acids of interest may be extracted from the egg shell membrane and purified for numerous uses. | 12-10-2009 |
20100137567 | PULVERIZER AND CORRESPONDING METHOD FOR PREPARING A BIOLOGICAL SAMPLE FOR PROCESSING - The invention relates, for example, to methods for preparing a plant or animal sample for processing, i.e. for example for the isolation of nucleic acids or proteins from the sample, as well as to a pulverizer. | 06-03-2010 |

20100298549 | Extraction method for target bio-molecule from a sample solution and fabrication of extraction module - An extraction method for a target bio-molecule of a sample solution is described. First, a substrate having a thermally responsive polymer brush immobilized thereon is provided. The thermally responsive polymer brush has a lower critical solution temperature (LCST). Thereafter, while the sample solution flows over the substrate, the temperature of the sample solution or the substrate or both is decreased to less than the LCST, so that the target bio-molecule of the sample solution is captured inside the thermally responsive polymer brush. Afterwards, while the extraction solution flows over the substrate, the temperature of the extraction solution or the substrate or both is increased to more than the LCST, so that the captured target bio-molecule of the sample solution is released out of the thermally responsive polymer brush. | 11-25-2010 |
20110046357 | HIGH PRESSURE REFOLDING OF PROTEIN AGGREGATES AND INCLUSION BODIES - The present disclosure provides an effective method for the refolding of denatured proteins in solution so that properly folded, biologically active protein in solution is recovered in high yield. The refolding takes place at pressures between about 0.25 kbar to about 3.5 kbar, advantageously at about 1.5 kbar to about 3 kbar. Typically a chaotropic agent is present at a concentration which is not effective for denaturing protein at atmospheric pressure, and optionally, oxidation-reduction reagents can be incorporated in the refolding solution so that native intramolecular disulfide bonds can be formed where that is desired. The method is applicable to substantially all proteins, especially after solubilization and/or denaturation of insoluble protein aggregates, inclusion bodies, or abnormal oligomeric (soluble) aggregates. | 02-24-2011 |
